At Princeton, Terrell majored in chemical engineering. A second tenor, he loved singing. As a member of the Smith-Princeton Chamber Chorus, he toured South America, singing in Chile, Argentina, and Mexico.
He later went to the University of Washington, where he earned a master’s degree in environmental science. Between his degrees, he worked for Procter & Gamble and was a named inventor on the first U.S. Patents for liquid Cascade and liquid Tide.
Music always remained important to Terrell, and he was the lead guitarist and vocalist with the Sydeways band. He was an avid skier and tennis player, as well as a referee for school soccer in Portland, Ore. Passionate about wine, he had more than 400 bottles in his wine cellar.
Terrell lived most of his adult life in Portland. He was married to Audrey Egli until her death. They had a son, Patrick. Later in life, he married Annette Mulee. The class extends its condolences to Annette, Patrick, and grandson Jack.
